摘　　要：分别采用GM(1,1)和Verhulst模型对建筑物沉降量进行预测分析。结果表明,两种模型预测各有阶段性利弊,在建筑物荷载稳定前进行沉降预测时,GM(1,1)模型的沉降预测效果较好;在建筑物荷载稳定后进行沉降预测时,Verhulst模型的沉降预测效果较好;最终沉降量应通过实地观测结果结合Verhulst模型的最终预测值来确定。在对建筑物沉降量进行全过程预测分析时,建议同时采用两种模型预测,并进行对比分析。In this paper,we used GM(1,1)and Verhulst models to predict and analyze the settlement of buildings.The results show that the two models have different pros and cons.When the settlement prediction is carried out before the building load is stable,the GM(1,1)model is better for settlement prediction.While,when the settlement prediction is carried out after the building load is stable,the Verhulst model is better for settlement prediction.The final settlement shall be determined by field observations in conjunction with the final predictions of the Verhulst model.In the whole process prediction analysis of building settlement,it is recommended to use both models for prediction and comparative analysis.
